Molybdenum Oxide
Covered in 1 MetalsCost.com News Intelligence article, most recently on August 26, 2026.
Overview
Molybdenum oxide is the roasted intermediate between mined molybdenite ore and usable molybdenum products. Mined ore is crushed, ground and floated to concentrate molybdenum disulfide to around 90% purity; that concentrate is then roasted in air, first converting to molybdenum dioxide and then, through the lower hearths of the furnace, to molybdenum trioxide. It is molybdenum's dominant traded intermediate form — most of the metal's supply chain runs through it rather than through metallic molybdenum directly.
How It's Made
Roughly 80% of roasted molybdenite concentrate goes on to become technical-grade MoO3 used directly as a steelmaking alloy input, converted into ferromolybdenum by reduction with iron oxide. The remaining share is upgraded further — by sublimation into purified molybdic oxide or by wet chemical processing into ammonium molybdate and other pure molybdenum chemicals — for catalyst, pigment, lubricant and specialty chemical uses outside the steel industry.
